Airport Security
I think with the heightened risk of terrorist activity especially after the Glasgow Airport car bombing any photographic activity could be seen as Photo Intel activity that could be used against us .
Best use the dedicated Air Park spotting spaces provided to photograph Aircraft ,
I agree that some Jobsworth’s can use the excuse of ‘security’ but its not worth the waste of breath trying to get a sensible answer as to the why’s and wherefores of civil freedom’s , considering all airport layouts and timetables are already in the public domain , other than pointing out to the aforesaid security person that theres ‘ NO’ notice’s to say you can’t look/photograph as you wish in a Public Area .
